Directions

Step one

Preheat oven to 375°F. Cut 1/4-inch slice from top of each onion; trim small amount from bottom end so onion stands upright. Place half of onions in 8x8-inch microwave-safe dish; add 1/2 cup water. Cover. Microwave on HIGH 10 to 12 minutes or until onions are tender. Carefully remove onions from dish and cool slightly. Repeat with remaining onions and water.

Step two

Carefully remove inner layers of onions with paring knife, leaving about a 1/4-inch onion shell. Chop and reserve 1 cup of the onion. Set aside remaining onion for another use.
